Comprehensive Guide to SAE AISI 1020 Steel Heat Treatment

SAE AISI 1020 mild steel undergoes meticulous heat treatment processes including normalizing, annealing, austenitizing, and more to enhance its properties.

Normalizing of AISI 1020: Achieving Optimal Performance

The ideal normalizing temperature for SAE AISI 1020 mild steel is 915 °C (1675 °F), ensuring peak material performance.

Art of Annealing AISI 1020 Steel

Explore the recommended temperature and cooling cycle for complete annealing of small carbon steel forgings (size ≤ 3 in.):
Engage in a precise annealing process at temperatures ranging from 855-900 °C (1575-1650 °F). The cooling cycle transitions from 855 °C (1575 °F) to 700 °C (1290 °F), with a furnace cooling speed of 28 °C/h (50 °F/h), achieving a Brinell hardness of 111-149 HB.

Mastering Reheating (Austenitizing)

Achieve optimal hardening by reheating (austenitizing) SAE 1020 steel at temperatures of 760-790 °C (1400-1450 °F). Enhance its surface through carburizing, typically performed at 900 to 925 °C (1650 to 1700 °F).

Surface Excellence with Case Hardening

The surface hardening carburization temperature of 1020 carbon steel ranges from 970-955 °C. This process is commonly executed in a mixed gas environment of methane and carrier gas. Post-carburizing, hardening is usually achieved by direct quenching from the carburizing temperature into water or brine, ensuring a robust surface finish.

Typical Heat Treatment for SAE 1020 Case Hardening

• The ideal carbon temperature range for SAE 1020 case hardening is between 900-925 °C (1650-1700 °F). For optimum results, a cooling method utilizing water or caustic solutions is recommended.
• Achieve superior reheat properties for SAE 1020 by maintaining a temperature of 790 °C (1450 °F). Cooling should be executed using water or a 3% sodium hydroxide solution to ensure quality results.
• For the process of carbonitriding, maintain a temperature ranging from 790-900 °C (1450-1650 °F) and utilize oil as the cooling method to achieve optimal surface hardening and durability.
• Applying a temper temperature between 120-205 °C (250-400 °F) contributes to stress relief and enhances resistance to cracking, though it is not mandatory, it can significantly improve material endurance.

Typical Forging Temperature

The optimal forging temperature for AISI 1020 mild steel is an impressive 1290 °C (2350 °F), known for facilitating excellent malleability and forming characteristics.

AISI 1020 Carbon Steel Welding

Recommended Preheat and Interpass Temperatures for AISI SAE C1020 Steel:
For materials with a thickness of ≤50mm (2 in.), the advised preheat and interpass temperature exceeds -12 °C for low hydrogen procedures and is set at 38 °C for applications other than low hydrogen.
For thickness ranges between 50 and 100 mm, a preheat and interpass temperature of 93 °C is crucial for low hydrogen processes, whereas 150 °C is recommended for non-low hydrogen applications.
Postweld heat treatment is an optional step; however, when implemented, the temperature should be maintained between 590-675 °C (1100-1250 °F) to enhance weld integrity.
